Summary | 07795: Qt debugger: Disassembly view glitch on bottom line | ||||
Description | By manipulating GUI controls, the Qt disassembly view will display an extra line of missing character symbols or a line duplicating the disassembly of a random earlier instruction. | ||||
Steps To Reproduce | Launch any driver with -debug, then move the scroll bar to the bottom on either the "dasm" part of the main window or a separate disassembly viewer, then click and drag the widget's bottom downward. Sometimes the phantom line will appear on its own. Clicking on the phantom line will cause the line above it to self-replicate. This likely reflects a buffer overrun of some sort. | ||||
Additional Information | This is almost certainly specific to the Qt debugger. The OS X debugger is not similarly affected. | ||||

Fixed in 86666f388eb8ee809a953e320acb828f2bd574c1. It was actually a core issue with it setting the origin to an out-of-range position. It’s masked in the macOS and Windows debuggers by other stuff they do on a view update. |
